(a) Interpretation: The index of hydrogen deficiency for the given compound is to be determined. Concept introduction: The index of hydrogen deficiency of a molecule is the extent to which the molecule is unsaturated. It is half the number of hydrogen atoms missing from the molecule as compared to a completely saturated molecule. The contribution of each double bond in a molecule to the molecule’s index of hydrogen deficiency is 1. The contribution of each triple bond in a molecule to the molecule’s index of hydrogen deficiency is 2. The contribution of each ring in a molecule to the molecule’s index of hydrogen deficiency is 1. If a molecule is saturated and has no rings, double bonds, and triple bonds, its index of hydrogen deficiency is 0.
